  • Assisted in securing a unanimous 6-0 defense verdict in a New Jersey premises liability case after the jury found no negligence on the part of the defendant. The plaintiff alleged that a six-foot drill bit fell from a retail display, causing a concussion, post-concussion syndrome and permanent cognitive impairments. The defense demonstrated that the item was displaced only after an unidentified customer struck the shelving with a shopping cart and that there was no evidence store employees knew or should have known of the condition. Through surveillance video, fact witness testimony and expert evidence, the defense also established that the impact was inconsistent with the forces necessary to cause a concussion and highlighted alternative explanations for the plaintiff's claimed injuries. Following a six-day trial, the jury returned a complete defense verdict, finding the defendant was not negligent.

    Assisted in securing a unanimous defense verdict in a premises liability matter involving a national home improvement retailer. The plaintiff alleged that she developed Complex Regional Pain Syndrome (CRPS) following a fall in the retailer's parking lot in October 2022. Plaintiff claimed that the incident necessitated significant ongoing medical treatment, including the implantation of a permanent spinal cord stimulator. The plaintiff sought substantial damages, including claims for extensive future medical care. The defense team successfully challenged the credibility of the plaintiff's allegations and expert testimony through rigorous cross-examination and the presentation of defense experts in forensic engineering, human factors, and pain management. The defense also demonstrated that the plaintiff's alleged condition was attributable to pre-existing medical issues rather than the incident at issue. Following a six-day trial, the jury deliberated for just 42 minutes before returning a unanimous verdict finding no negligence on the part of the defendant.

Appellate Division Affirms Dismissal of Legal Malpractice Counterclaim Against Martin Law Firm

In Martin v. Loury, 2026 N.J. Super. Unpub. LEXIS 1617 (App. Div. July 15, 2026), Martin Law Firm represented Kirk Loury in an employment matter Mr. Loury filed against his former employer, Concord Equity Group Advisors LLC (“Concord”). The allegations included, among other things, that Loury was not fairly compensated for his employment with Concord. After a bench trial finding in Loury’s favor, the Appellate Division remanded this matter in February 2016 for a second trial. During the second trial, Concord CEO, Lee Argush, testified to lower compensation estimate than first trial. On remand, the second trial judge awarded Mr. Loury the same damages as the first judge, finding Mr. Argush not credible. After the findings during the second trial, Martin Law Firm filed an action against Mr. Loury to recover legal fees and costs of representing Mr. Loury in a second bench trial and Mr. Loury filed a counterclaim against Martin Law Firm for legal malpractice, alleging he should have received an even higher award in the second bench trial. In this allegation, Mr. Loury, through his expert, claimed that Martin Law Firm should have recalled Mr. Loury to the stand to rebut Mr. Argush’s testimony to allege an alternative theory of damages. Mr. Loury’s expert admitted that the second judge already rejected Mr. Argush's theory and accepted Loury's damages theory. The trial court barred Mr. Loury’s expert and dismissed Loury's counterclaim with prejudice before convening the collection trial, and the jury ruled in Martin Law Firm’s favor. Mr. Loury appealed the trial court's pretrial rulings barring his liability expert from testifying in support of his legal malpractice counterclaim, denying his motion for summary judgment on that counterclaim, and denying his motion to amend his counterclaim by adding attorney Joseph A. Martin as a codefendant. In affirming the trial court’s decision, the Appellate Division held that the trial court properly excluded Loury’s expert testimony in the counterclaim against Martin Law Firm because the expert could not explain how calling Loury as a rebuttal witness would have increased damages when the second judge already rejected Mr. Argush's testimony and accepted Loury's damages theory, making the expert’s causation opinion speculative. The Appellate Division also held that the trial court properly denied Mr. Loury's summary judgment motion on his malpractice counterclaim because reasonable minds could differ on whether Mr. Martin's alleged failures would have changed the second judge's damages award, given the judge already found Mr. Argush not credible, creating genuine factual disputes precluding summary judgment. Also, the Appellate Division held that the trial court properly denied Loury's May 2023 motion to add Joseph Martin individually because the statute of limitations expired in February 2022, six years after the 2016 appellate remand when Mr. Loury incurred new legal costs, and relation back did not apply because Mr. Loury knew Mr. Martin's identity throughout and strategically chose to sue only Martin Law Firm in his 2019 counterclaim.
